IMPROVEMENT IN TIRE-BETTER.

TG ALL WHOM I'I-MAY OONCERN: I

Be it known that I, ROBERT OAWTIIORNE,.0` Lyons, Clinton county, State of Iowa, have invented anew and useful Device for Setting 'lire'on yWheels; and I do hereby declare that the following is a full, clear, and correct deseriptionoi the-same, reference being had to the accompanyingdrawing-s, and to letters of refe-rence marked thereon. i

The natnre of my invention censists'inarranging a tub of Water, with a circular platform made adjustable by means of a screw-standard passing through a step, and so arranged that after heating the tire and placing it en the wheel, it may he immersed in the water to cool and shrink uniformly.

It further consists. in n peeuliar arrangement'o' an adjustable nnt en the screw-stamlard and the platform, so as to regulate the dish of the wheel. It can be so arranged that any number of wheels can Ahe made to have precisely the same dish, thus having all the `wheels of a vehicle of a uniform dish, or without any dish, and by this convenient arrangement, enabling one to accomplish a large amount more of work in a given time, thus saving expense and furnishing a better quality ofiwerk.

In order to enable others to correctly understand my invention, andvto construct and use the same, I will carefully describe its construction and operation.

In the drawings, the same letters refer to the same partsof the device.

Figure 1 represents a top view or plan.

Figure 2 represents a vertiealseetien through the centre.

Figure 3 represents an elevation.,

A represents the tub or reservoir.

B represents ilange to tub.

G representsrests for platform.

D representsk a. tightening-nut with a'handle.

E represents a. screw-standard.

F represents the water.

H represents the step for standard E to work ini J represents the platform;

K represents the Wheel.

L represents thetire.

O represents the adjustablel nut.

I represents the frame for-platform.

R represents the Water-line.

S represents the braces that support the platform J'.

I construct the tub ir-reservoir A of any 'suitable material and any desired size. 'Io the bottom eti this tub, and in-its centre, I place a step, supported by legs, as indicated by Fig. No. 2 at I'I. In this step -I'put a standard, vfitting it to the step II hy means of a screw. 0n this standard I also.have a nut fitting the standard by means of s. screw, `as at O,.g. 2. Also, to this standard; I firmly attach the braces or arms that support the platform J', as shown at S, gp. I have fitted to the top of standard E 'av tail-nut, as shown at I), iig. 3. I

Aeonstruet rests For the platform, fitting the saineto turn easily on bolts, as indicated at c c c c, lig. 1, and the dotted lines there shown. v

New, the opera-tion of my device` is Aas follows: In order to set the tire and uniformly'adjust the dish of the'wheels, I place the Wheel4 on the platform J', the standard E passing through the huh. I turn th/e nut O np against the lower end ofthe huh, then I turn the tail-nut down firmly against the huhythus conning the Wheel against the platform J and the lmit O. Non', having the tire heated, I place it in its place on the rim of the Wheel, against the platform .T. Non, turn hack the standartlE-.so as to relieve the rests c c e c, turn them `as indicated by the dotted lines in iig. 1, then turn the platform J, ivith wheel K and standard E, clown the standard E, passing down through the step H, carrying with it the wheel on the vplatform into the water F,vas indicated by the dotted lines in tig. 2. The water quickly cooling the tire, it contracts, and the wheel being firmly confined in a. fixed position by nuts -O and D, it cannot twister dish only as designed in shaping the wheel, and loy the tire coming in contect with the water uniformly, it prevents burning the wood in one place while cooling-in another. New, it will be seen that anyl number of wheels een be made of precisely the same dish, for by turning the teil-nut D beek, the tire, in contracting, will make more dish by raising the hub against the nut. i

New, to remove the wheel turn the platform J up by turning beek the standard E, and it will carry up with it the wheel and the platform to the proper height forxests c c ec to come under it. Remove the wheel, and place onanother, pursuing the sume operatiom'and leaving the nut O in same place on standard E, the wheels will he all uniform in dish.

What I elaim es my invention, und desire to secure by Letters Patent, is-

vl. The rests c c c '0, for the purpose specified.

2. The arrangement unflfcombi'n'ation ofthe rests c e c c with the tub A, step H, standard E, platform J, nuts D anti 0, when operating substantially as and for the purposes herein set forth and specified.
